Explanation:

The term suspension means mixing of small and light particles together which are not dissolved in a fluid.

Therefore, clay, slit, and sand would be carried by suspension as they have small particles as compared to small pebbles and large rocks.

In a rock, there might be substance which are soluble in water. These soluble substances are therefore, continuously removed from the rock by the action of water.

Hence, holes will appear in the rock leading to rills and rough surface. Ultimately, the rock will either decompose or fall into pieces. On acidification of water by organic and inorganic solvents, the dissolution of rock increases.

Thus, it is concluded that in solution, rocks are dissolved by salts and acids.

Delvig [45]

B. Aquaculture means "cultivating small acreages of land."

Explanation:

Aquaculture is the growing of fishes, crustaceans, molluscs, oysters and other marine organisms like algae in a small acreage of farm. Normally, the carryign capacity per acreage would be lower in the natural habitat – like in the oceans- but this is raised substantially in aquaculture due to adopting certain farming techniques. An example is by cycling the wastewater from teh fish tanks to plants that take up the waste as nutrients and oxygenate the water, The water is then recycled back to the tanks as cleaner water reusable by the fishes and teh cycle continues. This cycle ensures the sustainability of the farm even with very little water compared to the natural environment.
